Instructions
Create a frame with the four pieces of scrap wood. Hold the frame together using the 3-inch screws. Fasten the plywood base to the frame using the 1 3/4-inch screws.
Measure the PVC pipe with the L Brackets. Drill four holes at equal distance from each other. Fix the L brackets to the PVC tube with the nuts and bolts.
Find the center point of the carpet. Use the PVC tube to measure to make a hole.
Use the carpet to gauge where the PVC pipe needs to be in the box. Position the pipe inside the box using the 3/4-inch screws.
Place the carpet over the pipe and into the box. Staple it to the base.
